2x-y=4
(i) put x=0
then,
2(0)-y=4
y=-4
(ii) put x=1
then,
2(1)-y=4
y=-2
(iii) put x=2
then,
2(2)-y=4
y=0
(iv) put x=3
then,
2(3)-y=4
y=2
Hence the four solutions are,
x=0,y=-4
x=1,y=-2
x=2,y=0
x=3,y=2
(i) put x=0
then,
2(0)-y=4
y=-4
(ii) put x=1
then,
2(1)-y=4
y=-2
(iii) put x=2
then,
2(2)-y=4
y=0
(iv) put x=3
then,
2(3)-y=4
y=2
Hence the four solutions are,
x=0,y=-4
x=1,y=-2
x=2,y=0
x=3,y=2
